# Loops - Read Numbers and Check Odd or Even Number

I have given here the code to read set of integers and display whether odd or even number.

## Source Code

#include <stdio.h>

int main()
{
printf("Program to find ODD or Even Number\n");
while(1)
{
int n = 0;
printf("\nEnter a number(-1 for Exit): ");
scanf("%d",&n);

if( n == -1)
break;

if((n % 2) == 0)
{
printf("%d is a EVEN number.\n", n);
}
else
{
printf("%d is a ODD number.\n", n);
}
}
return 0;
}

## Output

Program to find ODD or Even Number

Enter a number(-1 for Exit): 1
1 is a ODD number.

Enter a number(-1 for Exit): 2
2 is a EVEN number.

Enter a number(-1 for Exit): 3
3 is a ODD number.

Enter a number(-1 for Exit): 4
4 is a EVEN number.

Enter a number(-1 for Exit): 5
5 is a ODD number.

Enter a number(-1 for Exit): 6
6 is a EVEN number.

Enter a number(-1 for Exit): 7
7 is a ODD number.

Enter a number(-1 for Exit): -1

Press any key to continue . . .

1. #include

int main()
{
printf("Program to find ODD or Even Number\n");
while(1)
{
int i = 0;
printf("\nEnter a number(-1 for Exit): ");
scanf("%d",&i);

if( i == -1)
break;

if((i % 2) == 0)
{
printf("%d is a EVEN number.\n", i);
}
else
{
printf("%d is a ODD number.\n", i);
}
}
return 0;
}

2. ### cheak the number even or odd ###

#include
main()
{
printf("cheak number even or odd\n");
while(1)
{
int r=0;
printf("\n enter any number(-1 for exit) : ");
scanf("%d", & r );

if ( r== -1)
Break;

if((r%2)==0)
{
printf("%d is even number.\'n",r);
}
else
{
printf("%d is odd number.\n",r);
}
}
return 0;
}

3. #include

int main()
{
printf("Program to find ODD or Even Number\n");
while(1)
{
int x= 0;
printf("\nEnter a number(-1 for Exit): ");
scanf("%d",&x);

if( x == -1)
break;

if((x % 2) == 0)
{
printf("%d is a EVEN number.\n", x);
}
else
{
printf("%d is a ODD number.\n", x);
}
}
return 0;
}
